NU 420 M/C4VA301 Cylindrical Roller Bearing 100x250x58 Mm For Railway Vehicle Traction Motors

NU 420 M/C4VA301 Cylindrical Roller Bearing 100x250x58 mm For Railway Vehicle Traction Motors

Cylindrical Roller Bearing, NU420M/C4VA301, 100x250x58 mm, Brass Cage, Single Row, No Seal, Inner Ring - Both Sides Separable; No Snap Ring, Relubricatable, C4.

The NU420M/C4VA301 is a single-row cylindrical bearing with NU design. The outer ring of this bearing has two rigid ribs, while the inner ring has none. As a result, NU bearings are only capable of supporting radial forces. This bearing type is commonly used as a floating bearing. Floating bearings allow axial displacement of the shaft relative to the housing in both directions. This is necessary in applications where the shaft material shrinks or expands due to temperature changes (thermal expansion). NU bearings can also be used as support bearings by combining them with HJ angle rings (available separately). Support bearings can support radial forces and also axial forces in a single direction.

C4: Bearing Internal Clearance Greater Than C3.
